I build on openSUSE for three acrhs - ppc, ppc64, ppc64le. First two are OK and boot successfully. Third one does not work - it ends up in exception. I get initial GRUB greeting and that's all. Same problem I got with Vladimir libgcc patch series. It could be toolkit issue of course; but still it would need fixing before we can merge it. Could you help in debugging this issue? I have near to zero experience with PPC; I can do what you tell me, but not much more. I run it with qemu-system-ppc64 -M pseries -cdrom /tmp/grub2-ppc64le.iso -boot d Attached is screenshot of error.
